Formula
Tiles = ceiling of (room square feet ÷ tile square feet × (1 + waste)).
Cost = tiles × your price per tile. The flooring calculator path is the same math: a 7 inch by 48 inch plank is just a large tile in this formula.

Tile calculator and flooring calculator
This tile calculator counts pieces for a rectangular floor. Use it as a flooring calculator for any product you can describe by a length and a width, including plank, if you enter one piece's face.

Planning estimate from the numbers you enter. Coverage, density, waste and price are assumptions, not a supplier quote or an engineering specification.
How it works
Count is area divided by one tile, plus waste.
Room area is length times width in feet. One tile's area is its length times its width in inches, divided by 144, to get square feet. Divide the room by that area, multiply by 1 plus the waste percent, and round up. Ten percent is a starting waste for a straight set. A diagonal layout or a lot of cuts needs more. Grout joint width is not added. If the tile size you enter is the nominal size including the intended joint, the count follows that module. If you enter the actual tile and ignore a wide joint, you will be slightly long, which waste is meant to cover.

Example
A 12 by 10 foot room with 12 by 24 inch tile and 10% waste.
The floor is 120 square feet. Each tile is 2 square feet. The order is 66 tiles. At $4 per tile the material is $264. That does not include thinset, grout, or underlayment.

Tips
Buy the waste. Do not return the layout.
Dye lots differ. Ordering the exact net area and going back for a box is how floors end up mismatched. Niches, borders, and a second room should be their own areas. Add the counts.

Equipment
Flooring is a job. The saw is equipment.
Tile saws and other construction equipment used in a business can be part of a Dengaro application from $15,000 to $2 million. The tile count is a material estimate, not the amount to finance.
Important questions
Know what to expect.
Can this flooring calculator handle wood plank?+
Yes, if you enter the face size of one plank and a waste percent that matches the layout. Angle-cut floors often need more waste than a straight tile set.
Does the tile calculator include grout?+
No. Grout and thinset depend on joint width, trowel size, and the substrate. Use the coverage on those products after you know the area.
What waste percent should I use?+
Ten percent is the default for a simple rectangular layout. Increase it for diagonals, a small tile with many cuts, or a room that is not square. The field accepts 0 to 100.
Are the tile dimensions the box size or the actual size?+
Use the size of the face you will install. If the manufacturer says the nominal size includes the joint, decide whether you are counting the module or the tile, and stay consistent.
